Have you ever pined after someone to the point of feeling like you’re spending every waking moment thinking about them? Where you live your life in a loop of questioning how they feel about you—and any hint that it’s mutual feels euphoric, while anything to the contrary triggers a full-blown crash? Where you’re so consumed by the idea of them, “crush” just doesn’t really cut it?
If that sounds familiar, you might have experienced “limerence”—a term coined by the American psychologist Dorothy Tennov to describe an intense obsession with another person. The word has been gaining increased traction in recent years, both in research and culture.
So let’s back up. What exactly is limerence? Why is it so potent? And if you happen to be experiencing it—how can you break out of it?
What is limerence?
Named by Tennov in her 1979 book Love and Limerence, limerence is described as an obsessive, intrusive, and all-consuming romantic attachment to a person that is distinct from other feelings of love and desire.
Limerence does overlap with what researchers call “passionate love,” which is a standard but fiery and intense stage of early romantic relationships. But where the function of that love is ultimately to develop into a stable, secure bond, limerence thrives on uncertainty: It often stems from a pull toward someone who is unattainable or unavailable, or who is unclear about their feelings toward you. The greater the uncertainty, the stronger the feelings can become.
More on the differences between love and limerence later. But in short: When your feelings for this person are not able to develop into that stable bond, they can become disruptive, even debilitating—to the point where you’re struggling to go about your daily life for feeling so fixated on them.
And it’s not typically a short-lived experience, either. An average episode of limerence may last between 18 months and three years, though some have lasted up to seven years.
Signs of limerence: How to know if you’re experiencing it
In the midst of limerence, it’s common to channel all of your time and energy into obsessing over this person (referred to as the “limerent object” in psychology research). According to psychologist Dr. Roxy Zarrabi, this can take shape in a few different ways.
Disruptive thoughts
“Limerence involves obsessive and persistent thoughts about someone to the degree that it’s impacting your ability to focus on your own goals and other relationships in your life,” says Dr. Zarrabi. You might struggle to concentrate at work, and even neglect functional things like eating, sleeping, and hygiene.
Idealization
“You might find you’re idealizing the other person by focusing exclusively on their positive characteristics, and minimizing any red flags or signs that the person is not interested in you.”
Limerence can also involve projecting a pure fantasy onto this person, Dr. Zarrabi adds.
Intense mood swings
“Someone with limerence can experience a roller coaster of emotions that are dependent on whether the person they are interested in responds favorably to them or not,” says Dr. Zarrabi.
“There’s often an intense longing for their feelings to be reciprocated,” she elaborates—so you might overanalyze every interaction, becoming euphoric at perceived hints that there’s a chance, and despairing at any indication that there’s not.
What causes limerence? The psychology and neuroscience
Research on limerence is limited. But Dr. Zarrabi explains that the way limerence develops—and the reason it can become so intoxicating—is that if it goes on unresolved, it can begin to function similarly to an addiction.
“When you don’t know if your feelings will be reciprocated, the slightest hint of positive attention can feel special and exciting,” she explains. “This intermittent reinforcement can cause the person experiencing limerence to become dependent on the person’s validation or attention.”
Like with addictive behavior, contact with the limerent object can trigger the release of dopamine, the brain’s “feel-good” chemical. Because dopamine plays a key role in the brain’s reward system, this reinforces the behavior over time, driving a repeated desire to experience that same emotional high again. (And again. And again).
That said, limerence isn’t recognized as a psychological condition or diagnosis. It’s considered a descriptive concept.
Who experiences limerence?
Anyone can experience limerence. But researchers theorize that people with anxious attachment styles, lower self-esteem, neurodivergent conditions (like ADHD and autism), or certain mental health conditions (like anxiety, depression, OCD, and borderline personality disorder) may be more susceptible to it.
Again, there’s not enough research to definitively confirm these associations. But Dr. Zarrabi helps shed some light on hypotheses about why there may be a connection.
Anxious attachment
“People who have an anxious attachment style value a high degree of intimacy, but may also be subconsciously drawn to partners who are emotionally unavailable,” notes Dr. Zarrabi. This pairing may make them more prone to limerence, she says.
Given the overlap, some researchers actually conceptualize limerence as a form of anxious attachment. But other researchers disagree; a 2025 study, for example, found that while there was a correlation between people with anxious attachment and experiences of limerence, the link was only modest.
ADHD and autism
Both people with ADHD and autism can “hyperfixate”—or focus intensely—on certain interests, which has been theorized to lend itself to limerence.
Those with ADHD have also been associated with higher levels of "reward-seeking" personality traits, perhaps due to dysregulated levels of dopamine. This may make people with ADHD more susceptible to that addiction-like loop of limerence—where they become dependent on a person’s validation, and the “boosts” that come with it, Dr. Zarrabi says.
Low mood and self-worth
“If you’re feeling disconnected from others or unfulfilled in your life, limerence may serve as a distraction and temporarily feel like it’s filling that void,” says Dr. Zarrabi.
“If your self-worth is low, you may strongly crave validation from someone you’re uncertain will return your feelings,” she adds. One 2020 study found that self-esteem and relationship history (specifically the amount of breakups a participant had had) correlated with 20% of limerence cases.
But again, anyone can experience limerence. The 2025 study also included the experience of participants whose limerence seemingly came out of nowhere.
The stages of limerence: From infatuation to deterioration
Limerence is often described as a cycle. While different frameworks exist, most agree it tends to move through three core stages:
1. Infatuation
You feel an intense connection to a person, and become increasingly preoccupied with them. Positive interactions can feel euphoric, while perceived setbacks can feel disproportionately painful.
2. Crystallization
Your fixation hits a peak. Your thoughts and behaviors overwhelmingly revolve around this person, often at the expense of your own needs, and with a desperate desire for reciprocation.
3. Deterioration
If your feelings aren’t returned, the attachment begins to break down, potentially giving way to deep sadness, frustration, or resentment. In some cases, though, it can end more positively—if feelings are reciprocated and a healthy bond can develop, or you find a way to direct them elsewhere.
How does limerence differ from other types of attraction and connection?
Limerence vs. love—what’s the difference?
Limerence feeds off uncertainty and instability, whereas love requires more security and safety.
In limerence, you might obsess over how this person does or doesn’t feel about you. You tend to become fixated on an idealized version of them. And your intense desire for them and their validation can disrupt your life in a decidedly negative way.
Loving relationships, by contrast, are grounded in a shared reality, where feelings are shared and your perceptions of one another are more realistic. You share not only desire, but a deeper, more genuine emotional connection. And while love can have its ups and downs, overall, it’s a positive force in your life.
OK. What about unrequited love, you say? Well, unrequited love is considered to be less intense and all-consuming than limerence—and again, more grounded in reality rather than fantasy.
Does limerence turn into love?
Limerence can turn into love—if feelings end up being clearly reciprocated, the uncertainty ends, and a healthy, secure bond forms between you and the other person. But this might not happen, and often it isn’t possible. In that case, people need to find other ways to break out of limerence (more on that later).
Limerence vs. a crush vs. infatuation: Understanding the spectrum
A crush is relatively mild or fleeting. It can be understood as simply the experience of feeling attracted to someone, without much more to it. Crushes are often quite fun to have.
An infatuation is stronger. Maybe you think about this person a lot, fantasize about being with them, and it may border on obsessive—but the experience is typically relatively short-lived and superficial, without too much of a negative impact on your life.
Limerence is the most intense, long-lasting, and disruptive of the three versions.
Can limerence be platonic?
Limerence is typically understood in a romantic context, but anecdotally, people do report experiencing limerence-like obsessive attachment to friends, acquaintances, or platonic figures in their lives.
Since research is limited, we’re still learning about the different ways limerence might present for different people.
How to stop, overcome, and get over limerence
In his book Smitten, the neuroscientist Dr. Tom Bellamy—who has both studied and experienced limerence—offers some strategies for breaking out of it. Let’s talk about a few.
Recognize limerence for what it is
Limerence comes from a natural place. So first of all, don’t judge yourself.
It’s human to want others, and hope that they want us back. But when that wanting can’t turn into having—when limerence can’t turn into love—it’s worth taking a step back to recognize that the limbo of it all isn’t serving you.
Limit or break contact with your limerent object
This may involve blocking or muting them on social media, or avoiding or reducing in-person time together as much as possible. It may sound difficult (or unbearable), but it’s an important step in the process of detaching from the addictive feedback loop. The more the person’s out of sight, the easier it’ll be to get them out of mind.
Try mindfulness to interrupt intrusive thoughts
It’s okay if your limerent object pops into your head. It’s going to happen. But when it does, try a mindfulness technique to reground yourself in the present moment: wherever you are, name one thing you can see, one thing you can feel, one thing you can hear, and one thing you can smell.
Use the daymare technique to overwrite fantasies
The “daymare” technique involves intentionally turning a daydream into a nightmare scenario. Let’s say you catch yourself daydreaming about buying a house together—rewrite it so that they gamble all the money away and leave you high and dry.
If you find yourself replaying a positive interaction that you had with them in real life, try to bring to mind a negative memory about them, or remind yourself of all the times you’ve come away feeling bad after an interaction or obsessive thinking spiral.
Crucially: Channel your energy into other things
Distract yourself with new goals, hobbies, projects, or rewards that can give you a sense of purpose and meaning beyond this person. Plan things you can look forward to with friends or family. And dedicate time to self-care, including exercise and relaxation.
Limerence is a unique form of attraction and attachment that can feel all-consuming, and often debilitating. But you don’t have to be stuck in that place forever. Once you understand what’s driving it—the uncertainty, the reward loop, the fantasy of this person—it can get easier to step back and recognize it for what it is. With time, self-awareness, and an intentional focus on other things, limerence can gradually lose its intensity—so that what’s left is a steadier, more grounded sense of connection, whether it’s with yourself or someone else.
